Most likely Dovecot is still holding onto the file.  Sensible log rotation 
leaves the most recently rotated log uncompressed, in case the daemon is still 
holding a file descriptor.  Most programs (Dovecot included) allow you to send 
them a signal to tell them to release the log files.

I think someone else has already pointed out a SIGHUP should be enough.
